T0 all 'whom it may concern Be it known that I, HARLEY N. SICKLER, acitizen of the United States, residing at Buffalo, in the county of Erieand State of New York, have invented certain new and useful Improvementsin Slotting, Creasing, and Slitting Machines, of which the following isa specification.

My invention relates to slotting and creasing machines, and moreparticularly to machines for slotting and grooving paperboard,paste-board, packing-board, and the like.

The object of my invention is to provide a machine which will slot andgroove such board rapidly, accurately, and which is capable of being setto form slots and grooves as may be desired.

Further objects and novel features will be evident from the followingspecification and the drawings in which,-

Figure 1 is a side elevation. Fig. 2 is a plan view.- Fig. 3 is a rearelevation. Fig. 4 is a perspective of a piece-of board slotted andgrooved by my machine. Fig. 5 is a detail of my slotting and groovingwheels. Fig. 6 is adetail section of my slotting and grooving wheelstaken on a cutting radius. Fig. 7 is a similar detail taken on agrooving radius. Fig. 8 is an elevation of one of my cutting wheelsarranged for continuous cutting or slotting.

Referring first to Fig. 4, I will explain the function of my machine.This perspective shows a sheet or piece of board in which the outeredges 2 and 3 ha? been cut true-the board being designated by thecharacter 1. The slots 4, 4 have been formed and the uncut portionsbetween the two sets of slots have been grooved or pressed so that theboard will bend readily as shown at 5, 5.

Referring now to the other figures, the frame 6 of the machine has atable 7 upon which the sheets of board are placed one at a time. Journaled in this frame are shafts 8 and 9, upon which sprocket-wheels10, 10, 11,' 11 are rigidly mounted, and sprocket chains 12, 12, arecarried by these sprocket-v wheels. Secured tol the sprocket-chains 12,12, are feedin'gstrips 13,which feed the board to the rotating wheelsthat slot and groove the board. The machine is driven by a pulley 14which is belted to a source of power.

Mounted upon the shaft 8 is a gear 17 in mesh with 'a pinion 15 which isjournaled on the frame of the machine, and this pinion true the board 1on the edges 2 and 3 as itV is fed through the machine.

Rigidly mounted upon the shaft 18 are the wheels 24, each of which hasthe peripheral groove or slot 25 and the upstanding shear edges 26 and27. The width of the groove 25 is the width of the slots 4 to be cut inthe board 1.

Rigidly mounted upon the shaft 2O are f the wheels 28, which coact withthe wheels 24 to perform the slotting and grooving in the followingmanner: These wheels 28 are secured to their shaft by split-pulley hubs29, so that they may be adjusted to form the slots in the desiredplaces. Upon the peripheries of the wheels-28 areupstanding treads 29which are in planel with the upstanding shear portions 27 on'the wheels24. Mounted -upon the wheels 28. are shear segments 30 which are of thewidth of the groove 25 in the Wheel 24, and which are of the proper'tread length and properly positioned to cut out the pieces of the boardto form the slots 4, 4, and to force such cuttings down into the grooves25, as clearly shown in Fig. 6.

Secured to a truss 31 which is placed transversely of the machine justback of the wheels 28 are curved guides 32 which have their free endslying just above theftop plane of the board as it passes between thewheels. These guides hold the board down to prevent curling as it passesthrough the machine.

Mounted below and forward of the wheels 24 are Scrapers or cleaners 33,the free ends of which lie in the grooves 25 and clean out the cuttingsforced into said grooves by the shear segments 30.

The speed in revolution of the wheels 24 and 28 and the sprocket chains12, when two feeding strips 13 are used, is such that the travel is twoto one; so that the incoming boards are .properly timed to cause theshear segments 30 to cut the. slots 4 in the right places.

, The operation is as follows: A board being placed upon the table 7,one ofthe feeding strips. 13. strikes its rear edge and forces. itforward at tlifepropei'itime for a set of the shear Asegments Qand thewheels 24 to engage it and cut t i'lfo'rward slots 4, and at the sametime the shears21, 22 begin trimming the two edges 2 an'd'B. When theboard has advanced until the forward Aset of slots 4 havebeen cut, theshear members 27 on the wheels 24 and the treads 29 on the wheels 28press and groove the board .to form the grooves 5, as clearly shown inFlg. 7. At the proper interval the second setof shear segments 30 begincutting the rear set of .slots 4, and continue cuttmg until the boardpasses out completed; and during these several operations the shears-21,` 22 have completed the trimming of the edges 2 and 3; i

It will be understood that the wheels 24 and 28 are adjustable, as wellas radially,

upon their respective shafts, so that the slots 4 may be spaced asdesired. It will also be understood that shear segments 30 of varioustread lengths maybe employed to vary the lengths of the slots 4. Alsothat any desired numbers of pairs of wheels may be employed to make anydesired number of slots. f

It happensnot infrequently that I wish to cut from a single board morethan a single piece, cutting the board entirely through at some point.This I accomplish by securing to a wheel 28 a set of segments 30 asshown in Fig. 8,' so that it cuts continuously. On theother hand, I maywish to roove a board at some point entirely across 1t without formingany slots., This I am able to do by removing all of the segments 30 fromone of the wheels 28.

Having thus described my invention, I claim :-4
